Abstract (en)
[origin: EP1063060A2] A power tool for tightening and loosening threaded connectors has a link (1) having a link housing (2, 3, 4) and a ratchet mechanism (10) for turning an engaging element (11) so as to turn a threaded connector engaged by the engaging element, a first hydraulic drive unit (21) including a drive housing (22) and a hydraulically movable driving element (24), a second non-hydraulic drive unit (31) including a drive housing (32) and a non-hydraulically moveable driving element (35), a first connection (16, 26, 39) provided on the link housing (2, 3) and on the drive housings (22, 32) of the hydraulic drive unit (21) and the non-hydraulic drive unit (31), so that alternatingly either the housing (22) of the hydraulic drive unit (21) or the housing (32) of the non-hydraulic drive unit (31) can be connected with the link housing (2, 3), and a second connection (8, 27, 40) for connecting the ratchet mechanism (10) alternatingly with the driving element (24) of the hydraulic drive unit (21) or the driving element (35) of the non-hydraulic drive unit (31), so that the driving element (24) of the hydraulic drive unit (21) and alternatingly the driving element (35) of the non-hydraulic drive unit (31) during its movement turns the ratchet mechanism (10) of the link (1) and thereby turns a threaded connector engaged by the engagement element (11) of the link (1) to be tightened or loosened. <IMAGE>
